JaxPort will install technology on its diesel-powered cranes to reduce their pollution.

The JaxPort board voted Tuesday to accept a $588,235 grant that will pay for putting diesel oxidation catalysts on cranes and some equipment at the Talleyrand and Blount Island cargo terminals. No local match is required.

The Florida Department of Environmental Protection awarded the grant, which is funded by the U.S. Environmental Protection Agency.

EPA calculates the technology will make a 20 percent cut in emissions of particulate matter, 50 percent in hydrocarbons and 30 percent in carbon monoxide, according to JaxPort. The catalysts will be installed by mid-2013.

“We have long been in compliance with all clean air requirements and we are dedicated to doing our part as good stewards of the environment, whether we’re talking about air quality or the health of the river,” board Chairman Jim Citrano said in a statement.
